NNLL resummation for the production of four top quarks

Abstract
Four-top production is one of the rarest processes of the Standard Model observable at the Large Hadron Collider, offering sensitivity to the top Yukawa coupling, Higgs width, and beyond-Standard-Model physics. We present precise predictions for the invariant-mass distribution and total cross section using threshold resummation at next-to-next-to-leading logarithmic (NNLL) accuracy, matched to next-to-leading order (NLO) calculations.
